Capture duplicated records but I lost other columns

Hi all,

I have this situation in my input file:

For me a duplicated record is represented by only 3 highlighed columns.

My target is:

1. identity the duplicated record and move it into a flat file destination;

2. load the non-duplucated records into an ado net destination;

In this moment I'm using TSQL for duplication check, but we need to move this check into SSIS.

I tried to follow this tutorial:

https://www.youtube.com/watch?v=O4pf7m-VTSk

but it consider the entire record as a duplication.

When I try to use the tutorial above, I lost all other column and I can't map the input flat file columns with my ado net destination:

Is possible realize this with SSIS?

Thanks in advance.
